Camshaft Timing Oil Control Valve Assembly: Inspection

INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
1. Resistance inspection.
  1. Using an ohmmeter, measure the resistance between the terminals.
    Standard resistance: 6.9 to 7.9 Ω at 20°C (68°F)
2. Movement inspection.
  1. Connect the positive (+) lead from the battery to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve.
    NOTE: Confirm the valve moves freely and does not stick in any position.
    
    HINT:
    
    Dirt or foreign objects in the oil line cause the subtle pressure leaks in the valve. The pressure leak will cause the camshaft to advance. This condition will usually set a DTC.
